Description
上記目的を達成するために、本発明は、２つの被結合物を結合する舶用推進軸のリーマボルト結合構造であって、前記被結合物は、前記リーマボルトのリーマ部と所定の締めしろを有するボルト穴を有し、該ボルト穴は、前記リーマボルトの挿入始端部に、該リーマボルトのリーマ部外面と所定の隙間を具備するように拡径する穴逃し部を有し、前記リーマボルトは、前記リーマ部の挿入終端部に、前記ボルト穴の内面と所定の隙間を具備するように縮径するボルト逃し部を有している。この明細書及び特許請求の範囲の書類中における「挿入始端部」は、リーマボルトの挿入開始方向部分をいい、「挿入終端部」は、挿入終了方向部分をいう。これにより、リーマボルトのリーマ部がボルト穴に圧入される部分が、リーマボルトのボルト逃し部における挿入始端部側がボルト穴の穴逃し部における挿入終端部側に位置した時から始まり、リーマボルトが完全に圧入されてリーマ部がボルト穴に接した状態で終わるので、リーマボルトのリーマ部とボルト穴とのリーマ結合される距離が短くなり、リーマ部の圧入距離及び引抜き距離が短くなることで、リーマボルトによる結合フランジ等の被結合物を結合する結合作業及び分解作業の労力を大幅に軽減することができる。しかも、リーマ部の圧入距離及び引抜き距離を短くすることで発熱量が減り、リーマボルトの焼付きを抑止することができる。
In order to achieve the above object, the present invention is a reamer bolt coupling structure for a marine propulsion shaft that couples two coupled objects, and the coupled object is a bolt having a reamer part of the reamer bolt and a predetermined tightening margin. The reamer bolt has a hole relief portion that expands at an insertion start end of the reamer bolt so as to have a predetermined gap with an outer surface of the reamer bolt, and the reamer bolt includes the reamer portion. The insertion terminal portion has a bolt relief portion that is reduced in diameter so as to have a predetermined gap from the inner surface of the bolt hole. The “insertion start end” in the specification and claims refers to the insertion start direction portion of the reamer bolt, and the “insertion end portion” refers to the insertion end direction portion. Thus, the portion reamer section of the reamer bolt is pressed into the bolt holes, begins when the insertion start end portion side of the bolt relief portion of the reamer bolt is positioned on the insertion terminal end side of the hole relief portion of the bolt hole, reamer bolt is fully pressed Since the reamer part is in contact with the bolt hole, the distance between the reamer bolt and the bolt hole is reduced, and the press-in distance and pull-out distance of the reamer part are shortened. The labor of joining and disassembling work for joining objects to be joined such as flanges can be greatly reduced. In addition, the amount of heat generated can be reduced by reducing the press-fitting distance and the drawing distance of the reamer part, and seizure of the reamer bolt can be suppressed.
